Recent science educational policy reform efforts call for a shift toward practice-focused instruction in kindergarten–Grade 12 science education. We argue that this focus on engaging students in epistemic practices of science opens up new possibilities for the design of learning environments that support the stabilization of learners’ science-linked identities. Learning environments often assume that youth come to them without relevant identity resources to contribute or that the learning environment has no bearing on the disciplinary identification of individuals. We conducted this research while developing a year-long course to teach high school biology by engaging youth in interest-driven projects focused on contemporary topics. We explored how engaging youth in the epistemic practices of science in culturally expansive ways supported their science-linked identification. We propose a model grounded in social practice theory that describes aspects of students’ stabilization of disciplinary identities. We found that (a) deepening participation in scientific practices is linked to whether or not youth have opportunities to coordinate their engagement with their existing identities; and (b) material, relational, and ideational identity resources and qualities of the learning environment mediate how youth stabilize disciplinary identities in interactional moments.  相似文献

This paper presents an analysis of how affordances of ICT‐rich environments identified from a recent review of the research literature can support students in learning science in schools within a proposed framework for pedagogical practice in science education. Furthermore other pedagogical and curriculum innovations in science education (promoting cognitive change, formative assessment and lifelong learning) are examined to see how they may be supported and enhanced by affordances of ICT‐rich environments. The affordances that I have identified support learning through four main effects: promoting cognitive acceleration; enabling a wider range of experience so that students can relate science to their own and other real‐world experiences; increasing students' self‐management; and facilitating data collection and presentation. ICT‐rich environments already provide a range of affordances that have been shown to enable learning of science but integrating these affordances with other pedagogical innovations provides even greater potential for enhancement of students' learning.  相似文献

This article extends the discussion started by Margaret Beier, Leslie Miller, and Shu Wang??s (2012) paper, Science games and the development of possible selves. In this paper, I suggest that a theoretical framework based on a sociocultural theory of learning is critical in learning in a virtual environment. I will discuss relevant research on the application of various components of the sociocultural perspective of learning in classroom environments and the potential for applying them in virtual worlds. I propose that research in science education should explore the processes underlying cognitive apprenticeship and determine how these processes can be used in virtual environments to help students learn science successfully.  相似文献

In this paper, I employ situated learning theory to explore gendered processes of marginalisation and conscientisation in a social movement organisation. Using a student activist organisation as a case study, I explain women's awareness of and resistance to masculine performances of leadership and decision-making through the concept of gendered communities of practice and legitimate peripheral participation. I explore how gender inequality is performed in a community of practice, and how it both impedes and facilitates learning and resistance through legitimate peripheral participation. I attempt to bridge situated learning and conscientisation to better theorise the learning and resistance that occur when people are marginalised within communities of practice.  相似文献

This article discusses a case for a different, socio-cultural way of looking at learning progressions as treated in the next generation science standards (NGSS) as described by Ralph Cordova and Phyllis Balcerzak’s paper “Co-constructing cultural landscapes for disciplinary learning in and out of school: the next generation science standards and learning progressions in action”. The paper is interesting for a number of reasons, and in this response I will identify different aspects of the paper and link the points made to my own research, and that of colleagues, as complementary perspectives. First, the way that the science curriculum is conceived as an expanding experience that moves from the classroom into the community, across subjects, and across time, links to theoretical positions on disciplinary literacies and notions of learning as apprenticeship into the discursive tools, or ‘habits of mind’ as the authors put it, that underpin disciplinary practice. Second, the formulation of progression through widening communities of practice is a strong feature of the paper, and shows how children take on the role of scientists through this expanding exposure. I will link this approach to some of our own work with school—community science partnerships, drawing on the construct of boundary crossing to tease out relations between school science and professional practice. Third, the demonstration of the expansion of the children’s view of what scientists do is well documented in the paper, illustrated by Figure 13 for instance. However I will, in this response, try to draw out and respond to what the paper is saying about the nature of progression; what the progression consists of, over what temporal or spatial dimensions it progresses, and how it can productively frame curriculum processes.  相似文献

Mathematics, seen as a model of pure science, often conveys the image of a science constructing itself in quite poor technological environments; it nevertheless develops by elaborating (and by exploiting) powerful material and symbolic tools. Actually mathematics teaching is closer to this image of mathematics than to mathematical practice: its goal seems to transmit a form of culture rather than efficient computation tools and theoretical means of their control (Kahane, 2002). This situation is viable if the tools can be held at distance, outside the classroom; it is no longer viable when computation tools (essentially calculators) are imported by students themselves inside the classroom and integrated into their mathematical practice. Thus established conflict between the social legitimacy of these tools and their school illegitimacy (Chevallard, 1992) deeply destabilises mathematics teaching itself. We present here a general framework to think about the integration of the tools in the teaching and learning of mathematics. More precisely, we propose:
  1. A theoretical approach, which allows us to understand the influence of tools on human activity and in particular on professional and school education processes;
  2. An analysis of computerized learning environments, which shows the importance of students' control of their own activity;
  3. Some elements that help to think about the temporal and spatial organization of study in such environments and to guide students' activity;
  4. A reflection about the conception of pedagogical resources, which is all the more necessary if one wants to facilitate an evolution of teachers' practices.

We have designed a model for transformational science teaching focused on linking theory and practice through curriculum decision making that has been the framework for professional development sessions for middle-grade science teachers during the past 5 years. Interviews with teachers revealed that their experiences with curriculum development were of significant value in making decisions concerning the design of classroom environments. As teachers reflected on current research about teaching and learning, in collaboration with university scientists and science educators, they were informed by theoretical perspectives which held implications for their practice. Curriculum development became a vehicle for professional development and school reform; however, it was vital that the teachers were in clear communication with their administrators and communities concerning reform issues. Students and teachers from schools implementing the model and from control sites were interviewed to determine the model's influence on instructional practices and student attitude and achievement in science. The five-phase model for transformational science teaching is discussed here, accompanied by teacher comments about tensions experienced at each phase. This discussion is followed by an analysis of teacher and student interview data that reveals teachers' use of instructional strategies and students' attitudes toward science. Results and analysis of student performance on a mandated end-of-grade science test are also included. From this evidence, we recommend a new design for professional development opportunities for teachers that engages them in decision making as they reflect about the connections between theory and practice and the value of continually testing, revising, and reevaluating curriculum and instructional issues.

While astronomy has recently re-emerged in many science curricula, there remain unresolved teaching and learning difficulties peculiar to astronomy education. This paper argues that mental model building, the core process in astronomy itself, should be reflected in astronomy education. Also, this crucial skill may promote a better understanding of the nature of science by pupils and it resonates with current understandings about pupils' learning in science. However, three practical questions to be considered are: the expressed reservations about the connection between mental model building and meaningful learning; the earliest age of pupils for whom mental model building is appropriate; and the lack of research into pupils' prior ideas about the role of models in science. The paper describes how a four-phase general pedagogical strategy was adopted to create an astronomy teaching and learning package to promote mental model building. The package consists of notes explaining the mental model building followed by an overview of the teaching-learning approach and suggested outlines of the 12 lessons. Research investigated whether that package can help Year 7-8 pupils interrogate and refine their mental models of the Sun-Earth-Moon system within the constraints of an ordinary class of 33 pupils. The results showed that all four phases of the general strategy were necessary and effective in that most pupils were able successively and successfully to critique their mental models of the Sun-Earth-Moon system while also achieving traditional astronomy knowledge goals. Implications are that pupils as young as Year 7-8 may be able to construct other appropriate mental models, such as those for biological populations, atomic structure and plate tectonics.  相似文献

In this paper, we identify beliefs about teaching and patterns of instruction valued and emphasized by science, technology, engineering, and mathematics faculty in higher education in the USA. Drawing on the notion that effective teaching is student-centered rather than teacher-centered and must include a balance of knowledge-, learner-, community-, and assessment-centered learning environments; we use qualitative interview data to explore how faculty's reported beliefs about teaching are associated with their consideration of these four types of environments. Findings indicated that although a range of beliefs about teaching emerged, most were firmly located in knowledge-centered learning environments, with little or no focus on the remaining three learning environments. Furthermore, even patterns of instruction that were heavily student-centered were situated within a knowledge-centered learning framework. We argue that for student-centered instruction to be truly successful, faculty must consider all four learning environments in crafting and facilitating the classroom environment.  相似文献

In this review, we explore the notion of teaching science to English language learners (ELLs) as a balancing act between simultaneously focusing on language and content development, on the one hand, and between structuring instruction and focusing on student learning processes, on the other hand. This exploration is conducted through the lens of a theoretical framework embedded in the Science Writing Heuristic approach, an approach exemplifying immersive orientation to argument-based inquiry. Three learning processes (learning through the language of science, learning about the language of science and living the language of science) and three classroom structures (collective zone of proximal development, symmetric power and trust relationships and teacher as decision-maker) are explored in relation to learning theories and empirical findings from second language acquisition and science, multicultural and teacher education bodies of work. Three themes – negotiation, embeddedness and non-threatening learning environments – to inform ELL science education emerged from the review.  相似文献

This study explores the relationship between interaction rituals, student engagement with science, and learning environments modeled on communities of practice based on an ethnographic study of an eighth grade urban magnet school classroom. It compares three interactional events in order to examine the classroom conditions and teacher practices that can foster successful interaction rituals (IRs), which are characterized by high levels of emotional energy, feelings of group membership, and sustained interest in the subject. Classroom conditions surrounding the emergence of successful IRs included mutual focus, familiar symbols and activity structures, the permissibility of some side‐talk, and opportunities for physical and emotional entrainment. Sustained interest in the topic beyond the duration of the IR and an increase in students' helping each other learn occurred more frequently when the mutual focus consisted of science‐related symbols, when there were low levels of risk for participants, when activities involved sufficient challenge and time, and when students were positioned as knowledgeable and competent in science. The results suggest that successful interaction rituals can foster student engagement with topics that may not have previously held interest and can contribute to students' support of peers' learning, thereby moving the classroom toward a community‐of‐practice model. © 2006 Wiley Periodicals, Inc.

The ubiquitous goals of helping precollege students develop informed conceptions of nature of science (NOS) and experience inquiry learning environments that progressively approximate authentic scientific practice have been long-standing and central aims of science education reforms around the globe. However, the realization of these goals continues to elude the science education community partly because of a persistent, albeit not empirically supported, coupling of the two goals in the form of ‘teaching about NOS with inquiry’. In this context, the present paper aims, first, to introduce the notions of, and articulate the distinction between, teaching with and about NOS, which will allow for the meaningful coupling of the two desired goals. Second, the paper aims to explicate science teachers’ knowledge domains requisite for effective teaching with and about NOS. The paper argues that research and development efforts dedicated to helping science teachers develop deep, robust, and integrated NOS understandings would have the dual benefits of not only enabling teachers to convey to students images of science and scientific practice that are commensurate with historical, philosophical, sociological, and psychological scholarship (teaching about NOS), but also to structure robust inquiry learning environments that approximate authentic scientific practice, and implement effective pedagogical approaches that share a lot of the characteristics of best science teaching practices (teaching with NOS).  相似文献

Although pedagogical approaches drawing on constructivist learning theories often place students in environments that are to resemble professional knowledge-building communities, paradoxically, they also orchestrate students' re-constructions to harmonize with canons of Western science. Under the cover of social-constructivist epistemologies and Vygotskian pedagogies, students' prior conceptions are denigrated, their experiences regulated, their investigations shepherded, and their conclusions restricted. Such actions are undemocratic-citizens' literacy is confined to that narrowly defined by society's e´lite and, therefore, is not egalitarian. Students have few opportunities to become self-actualized-to develop in ways unique to their needs, interests, abilities and perspectives. After elaborating these concerns, I provide a framework for curriculum development that may help democratize science education. It is an approach that gives priority to personalization, inclusion, problematization, explicitness, apprenticeship, authenticity and freedom.  相似文献

Informal learning experiences have risen to the forefront of science education as being beneficial to students' learning. However, it is not clear in what ways such experiences may be beneficial to students; nor how informal learning experiences may interface with classroom science instruction. This study aims to acquire a better understanding of these issues by investigating one aspect of science learning, scientific reasoning ability, with respect to the students' informal learning experiences and classroom science instruction. Specifically, the purpose of this study was to investigate possible differences in students' scientific reasoning abilities relative to their informal learning environments (impoverished, enriched), classroom teaching experiences (non-inquiry, inquiry) and the interaction of these variables. The results of two-way ANOVAs indicated that informal learning environments and classroom science teaching procedures showed significant main effects on students' scientific reasoning abilities. Students with enriched informal learning environments had significantly higher scientific reasoning abilities compared to those with impoverished informal learning environments. Likewise, students in inquirybased science classrooms showed higher scientific reasoning abilities compared to those in non-inquiry science classrooms. There were no significant interaction effects. These results indicate the need for increased emphases on both informal learning opportunities and inquiry-based instruction in science.  相似文献

In this research project, we investigated two beginning secondary science teachers' efforts to learn to teach science in ways that build from and celebrate the ethnic, gender, linguistic, and academic diversity of their students. To do so, we followed Troy and Brian from their preservice teacher education experiences through their first year of teaching 8th grade physical science at local junior high schools. We also conducted a follow‐up observation and interview with each participant after he had moved past the beginning stage of survival in the teaching profession—once in his fourth year of public school science teaching. Through qualitative analysis of interviews, classroom observations, and teachers' written work, we identified patterns and explored commonalities and differences in Troy and Brian's views and practices tied to equity over time. In particular, we examined successes and challenges they encountered in learning to teach science for all (a) from their students, (b) from inquiry into practice, and (c) from participation in professional communities. In our implications, we suggest ways teacher educators and induction professionals can better support beginning teachers in learning to teach science to all students. In particular, we highlight the central roles both individual colleagues and collective school cultures play in aiding or impeding beginning teachers' efforts to learn from students, from practice, and from professional communities. © 2006 Wiley Periodicals, Inc.

Metacognition and self-regulation are important for developing effective learning in the classroom and beyond, but novice learners often lack effective metacognitive and self-regulatory skills. However, researchers have demonstrated that metacognitive processes can be developed through practice and appropriate scaffolding. Betty’s Brain, an open-ended computer-based learning environment, helps students practice their cognitive skills and develop related metacognitive strategies as they learn science topics. In this paper, we analyze students’ activity sequences in a study that compared different categories of adaptive scaffolding in Betty’s Brain. The analysis techniques for measuring students’ cognitive and metacognitive processes extend our previous work on using sequence mining methods to discover students’ frequently-used behavior patterns by (i) developing a systematic approach for interpreting derived behavior patterns using a cognitive/metacognitive task model and (ii) analyzing the evolution of students’ frequent behavior patterns over time. Our results show that it is possible to identify students’ learning behaviors and analyze their evolution as they work in the Betty’s Brain environment. Further, the results illustrate that changes in student behavior were generally consistent with the scaffolding provided, suggesting that these metacognitive strategies can be taught to middle school students in computer-based learning environments.  相似文献

In this study, the concept of ‘community of learners’ was used to improve initial vocational education. The framework of a ‘community of learners for vocational orientation’ that we present offers both a theoretical understanding of teaching–learning processes in initial vocational education and heuristics for the design of innovative learning environments for optimising these processes. In a design research study, we investigated if, and how, learning environments designed on the basis of these heuristics fostered communities of learners for vocational orientation, in which students experience to learn in a shared, meaningful, reflective and transfer-oriented way. We examined students’ perceptions of the learning environment and their learning activities during eight curriculum units specifically designed to foster the communities of learners. During almost all of the units that we designed, students found themselves learning in a more shared, meaningful, reflective and transfer-oriented way than during regular units. We conclude that the proposed heuristics had been useful starting points for the design of innovative learning environments that foster communities of learners for vocational orientation. In addition, we show how the heuristics can be elaborated for a particular school, based on practical and pedagogical content knowledge of teachers, as well as students’ perceptions of the learning environment and their learning activities.  相似文献
